Popping out of 4th Gear

Popping out of 4th Gear
1966 Muncie M21. New synchros, bearings, gaskets and seals. Shifts great, Linkage adjustment feels spot on. 442 Shifter rebuilt, no vibration of stick or drive line. 80-90wt dino fluid full. Wants to pop out of 4th gear upon decelleration. Goes back in to gear fine, but still wants to pop out. When I get under the car and move the linkage, it sounds and feels like it goes in to 4th just like 3rd. Help.

When a transmission pops out of gear it is normally caused but a worn slider and bad small engagement teeth on the gear, in your case the input gear.
Here are some pictures that might help.
These are from a two articles I wrote, disassembly and inspection of a T-10, which is very similar to the Muncie.
